Why does Poku exist?

Poku makes testing easy and takes on the testers' difficulties to let you focus on your tests:

No configurations
      Auto detect ESM and CJS
      Auto detect Typescript files
      Run the same test suite for Node.js (6+), Bun and Deno

Easier and Less Verbose
      Node.js familiar API
      Instantly re-run related tests in watch mode
      Run CJS (CommonJS) files directly with Deno
      Easily handle, servers, services, processes, and ports

Safety and Reliability
      High isolation level per file
      Performant and lightweight
      Compatible with coverage tools

💡 Poku brings the essence of JavaScript back to testing, allowing to use your knowledge to create tests intuitively.
